Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a pipe jacking machine for water conservancy construction. Background Art

[0002] Pipe jacking refers to a concealed excavation construction method used when tunnels or underground pipelines pass through various obstacles such as railways, roads, rivers or buildings. During construction, the pipe is pressed into the soil layer by a hydraulic jack supported on the back seat of the foundation pit through force-transmitting jacking irons and guide rails, and the soil in front of the pipe is excavated and transported away. Therefore, it is necessary to design a pipe jacking machine for water conservancy construction.

[0003] Construction workers generally use pipe jacking machines to carry out pipe jacking construction. Pipe jacking machines can provide power for pipes and push the pipes into the soil. However, most of the existing pipe jacking machines are not equipped with a height adjustment mechanism. As a result, when the pipe jacking machine is used to push pipes of different heights, it is necessary to use other lifting work to facilitate the lifting of the pipe jacking machine. This operation method is relatively cumbersome, which increases the cumbersomeness of the adjustment and use of the pipe jacking machine in the later stage. Moreover, the pipe jacking machine is mostly placed directly on the ground for use, and the direct placement has a poor stability effect. Accidental collisions will cause the pipe jacking machine to deviate, affecting the accuracy of the later pipe jacking. Utility Model Content
